I recently tried to play the game's multiplayer via Discord call, and discovered a really annoying problem.
While with the use of an external program, the game DOES pick up audio from external apps such as Discord as if it were microphone audio--It does not allow for two microphones to play the same round.
This is despite the game's multiplayer screen having a microphone option, being able to select an individual microphone for each player. No matter what I do, the game only picks up on whatever microphone is selected in the options menu, even on the player who has the other one selected.
Both microphones work completely fine with the game when selected via the options menu, but not when they are only selected on the multiplayer screen.
This issue persists between 4.14 and 5.1, as those are the only two versions I tested (one being the first I downloaded upon buying the game, the second just now for the purposes of testing)
Outside of this niche scenario, the game is still very fun and very playable, but the option for every player to have their own microphone is rather misleading when it doesn't even work.
